Course detail

Physics for Audio Engineering

FEKT-JFYZAcad. year: 2018/2019

This course is a basic course of physics, focusing on areas usable in the sound technology. The first part is focused on the basics of particle mechanics, force and motion. The following areas are harmonic, damped and forced oscillations, then progressive and standing waves, the energy transmitted by waves, superposition and interference of waves. Physical fields are next areas which will be discussed. Gravitational field will be mentioned briefly. Electric and magnetic fields will be discussed in more detail, students will spend their formation, properties and basic laws and also generation of electromagnetic waves. This course will familiarize students with basic physical principles used in the measurement of non-electrical quantities by electrical methods. The last part of the course is focused on limits of classical physics and outline of their overcoming.

Aims

The aim of the course is to provide students with a clear and logical interpretation of the basic physical concepts and laws focusing on areas utilized in the audio technology. There are mainly a particle mechanics, oscillations, waves, electric and magnetic fields. Understanding of these concepts and laws will be strengthened through a wide range of interesting applications. Practical knowledge will be verified in the laboratory exercises.
